Course Overview
Learn how to develop maintainable software systems applying Design Patterns based on Meta and SOLID Principles
SOLID is an acronym which stands for SRP, OCP, LSP, ISP and DIP. These five acronyms in their turn stand for:
Single Responsibility Principle
Open/Closed Principle
Liskov Substitution Principle
Interface Segregation Principle
Dependency Inversion Principle
In this course, you’ll learn how to apply meta and SOLID principles so that your application will live a long healthy life. It means you are going to learn how to write code of the high quality: readable, understandable and reliable.
Improve your knowledge in object-oriented programming
Understand the meta principles on which all the other development principles are based
Understand the symptoms of code defects
Learn the foundations of SOLID principles
Learn how to detect the violations of SOLID principles and how to fix the problems
Learn how meta principles and SOLID principles are related to each other and how to find the balance between them
Foundations of writing object-oriented code
Despite the fact that C# is a very rich on features language, it's very common to see poorly designed and implemented applications in a real world. Language by itself does not guarantee that the architecture of an application will be great. In order to design and build maintainable software, we need to understand the principles of software development. This video course is exactly about how to achieve clean and maintainable software.
You probably have already heard the following well-known statement: most code sucks. Well, this course is all about how to produce code which doesn't suck.
Owning skills of producing a well-designed and well-implemented types is the prerequisite for the other developers to treat you as a decent professional.
Content and Overview
This course is aimed at middle and senior developers. Solid experience in C# is required.
There are plenty of code examples throughout this course so that you will learn both theoretical and practical material.
Starting with SOLID principles we will go further to the meta-principles. Going through the SOLID principles, you’ll also learn about the related patterns. Then we will get to the problem of contradictions between different principles. You’ll learn about the relationships between SOLID principles and meta principles.
In general, you’ll learn in this course:
SRP
OCP
LSP
ISP
DIP
These are the SOLID principles. You’ll learn the background problems that can be solved by particular principle, you’ll see the demonstrations in code, you’ll learn the related patterns to every principle.
Learning DIP you’ll in addition learn what is Dependency Injection, Inversion of Control, IoC-Containers and what are the architectural implications of DI.
Here are other topics you’ll learn in the course:
DRY – don’t repeat yourself
KISS – keep it simple stupid
YAGNI – You Ain’t Gonna Need It
SoC – separation of concerns
CQS – command query separation
Law of Demeter
Principle of Least Astonishment
Information Hiding and Encapsulation
API Development Principles
Contradiction between SOLID and YAGNI
Contradiction between OCP and YAGNI
What is Architecture and Design
Teaching Approach
No fluff, no ranting, no beating the air. I respect your time. The course material is succinct, yet comprehensive. All important concepts are covered. Particularly important topics are covered in-depth.
Take this course, and you will be satisfied!

What You’ll Learn
- Determine if a class has too many responsibilities, Apply SRP to make classes more granular, Determine the smell of duplication caused by OCP violation, Apply OCP to remove or prevent duplications, Make client's lives more enjoyable by applying ISP, making interfaces more granular, Determine LSP violations which break client's code, Apply LSP to come up with proper inheritance, Apply DIP to develop plugin architecture, Build your own simple IoC-Container, Build clean API in C#, I'm tired to list all the stuff you'll be able to do after this course )))

provides good direction on how to think while designing, as Mr Spock told rightly that my friends comes with PRACTICE :).

Good explanations in detail. Lack of clear examples, that illustrate the point. Sometimes, having smaller examples helps to understand big picture.

The examples and demonstrations are very good however, in some places it would have been great to provide simple examples like we had for square and rectangle to explain the principle. Since, the people who has a banking domain would most likely understand the examples for banking terminal. Hence i have given 4.5 otherwise its a 5 start course.

Overall, the instructor did OK, it's a shame really because the course could have been so much better if the coding examples were improved. The principles, definitions, backgrounds, pros/cons, and applicable design patterns were covered EXCEPTIONALLY well. HOWEVER, when it came time to showing application of a principle, the instructor dived directly into showing the use of each principle using a coding example that was too complex to begin with. Even as an experienced developer I found the jump from theory to immediately complex real-world code example to be a bit much. I would have liked the instructor to show a simplified coding example first, using a memorable example, before diving into the complex examples.
